IMPROVE) TURNOUT FOR 'RAITJRDJAJJSl SPECIFICATION- TO ALL WHOM IT MAYCONCERN: p

Be it known that I, SAMUEL A. OTIS, of Boston, in the county of Suffolk,and State of Massachusetts, have invented an improved Turnout; and I dohereby declare that the following is afull and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

Nature. The nature of my invention consists in combining and arranging,with fixed or dummyrswitchesfa system of rails of such a nature that thewheels upon one side of a car shall run upon their fia-ngeswhilethoseupon` the other side shall run upon their treads,`the whole socombined that as soon as the car is suiciently turned out of the lineoi' the main track it runs upon the points of the dummy switches and isthus conducted ofi' on to the sideling or turnout. The object of firstturning the car slightly away from the straight or main track is. i"that the fixed points of the dummy'switches may be outside of thelineof` the main track,` so that the returning `car (on the main track)may not have to run over the point of the dummyas is now the `case`Where a drop p dummy is in use. The advantage that my invention hasover that for which a patent was granted to J. Herbert Shedd and WilliamEdson, January 24, 1860, is that I do not have to curve the main trackat a1l,i`and `thus ,I i

save the shock that the return car receives when passing the Shedd &Edson switch( To enable others skilled in the art to make and use myvinvention, Iwill proceed to describe its` construction and use.

Drawings.

Figure 1 `represents a pair of ,car wheels, of which W runs upon itstread, and W upon its ange.

Figure 2 shows a 'turnout with my improved arrangement of switch-irons.i i i Figure 3 represents a cone upon a plane` surface, and is shown inconnection with my turnout simply to show the principle of action uponwhich my improvement is based. i

I lay a turnout track, B, in connection with the main track, A, with anyof the usual curves 'and frogs; the end F of the turnout is providedwith ordinary inlet dummy switches, O Of; the end E of `the turnout isrepresented as provided with my improved switch-irons, T and T. Thepiece T is perfectly flat, having ar cross-section, shown at T', fig. 1,and of about ten feet in length; upon this piece the iangesonly of the lwheels run. The other switch-iron, T, is made in the usual form of a fixdumrhy; the exact shape `and i length of both of these switches will ofcourse vary with the style of rail used.r

' The working of my switch is this: A car coming in the directionindicated by the arrow, (i, strikes the i switch-iron, T, and the wheelsof one side of the car` run upon theiranges, as shown by W and T, iig.1, while the other wheels run upon their treads, as shown by W and T, g.1, the effect of whichiisto make the car cone or run on avcurve, asindicated by the dotted line on the'Yswitch-iron T and by the arrow` C.

\ Claim.` What I claim as my invention, and desire to secure by LettersPatent, is- The combination of the device described for turning the carout of the straight line,vwith the fixed points of the dummy switches,as shown and described. y
